I have a 2016 T150 cargo with the standard radio. The rearview monitor is in the mirror and it is very good. I wish I could also manually turn it on at times to check the wider view the camera provides. Since the large rear windows get dirty and my cabinets obstruct the rear view mirror view a little, I find the camera view helpful. In my previous E250, I installed a review camera in the rear door and manually controlled it and it was very helpful. On my T150, I installed a small camera on the passenger side to give me a view in parking lots to help when backing. I control that camera.
2016 T150 , 130 wb, 3.31, Ecoboost, trailer tow package, rear glass.
